ArchiCAD 20 and upcoming Apple MacOS Sierra release.

[Anonymous]

Our office schedules OS updates and software upgrades based on compatibly assurances. Based on when we think these things are going to happen we would then decide to make new hardware/software purchases in 2016 or in 2017.
While nothing is ever "for certain" and no one can foresee the impact a new OS version will have on a major updated software release --has ArchiCAD 20 been tested on the Apple MacOS Sierra Beta? If so is this currently on going and about how long after does ArchiCAD hope to list a compatibility report or estimate an update/hot fix. As a new(er) ArchiCAD user is the track record that these things happen fairly quickly or is there usually a considerable lag-time?
Cheers.

Graphisoft has historically, consistently, tested each current product release - as well as typically at least the previous version - with every new OS and publishes a product update/hotfix after the new OS is officially released. Historically, the internal builds developed for a beta release of an OS are not made available to the public. Also, historically, the hotfix for compatibility with the new OS has not been released on the same day as the new OS X release because often Apple does not provide the final release (gold master) to Graphisoft with sufficient time for final testing.

For example, El Capitan was officially released by Apple on 9/30/15. Graphisoft released a public beta of 19 with El Capitan compatibility within weeks of that date. Update 5005 to AC 19 for full El Capitan compatibility (and lots of other fixes) was released on 2/16/16..
